u APPARATUS*FOR TIPPING AND DISCHARGING RAILWAY CARS.

Application tiled May 12, 1928, 'Serial No. 277,282, and inGreat'Britain February 1, 1927.

This invention relates to an apparatus for tipping and dischargingrailway cars suffi' The invention has for its object to providesimplified means for easily and securely supporting the car during thetilting operation.

According to the invention, ar cradle or frame is provided, same beingadapted to engage with and support the car upon one side and the topduring the tilting operation, the said cradle being arranged to rock orroll along a predetermined inclined path until the supported car isinverted andits contents discharged, after which the cradle is returnedto its normal position and the empty car is lowered to the tracks. Thecar may be inserted into the cradle by any suitable'means while it willbe seen from the description hereinafter given and the drawingaccompanying same, that the cradle may readily be mounted at anyrequired position above the railway track so as to allow of the carbeing hoisted to a desired height before tilting and discharge occur.

In the drawing: l

Fig. 1 is a side elevation ofmy improved tilting apparatus, showing acar in dotted lines drawn up into position to be tilted by the tiltingapparatus.

Fig. 2 is a front elevation of the same, the car being omitted. f

' 1 indicates conventionally a frame, onY

which the tilting apparatus lis mounted. The Vtop of the frame inclinesupwardly as `at 2 and is provided 1 with two rows of spaced apart-pins3.

4 indicates a cradle, comprising end pieces 5 and connecting bars 6.Each end piece comprises a body portion which is rounded on one edge toform a rocking surface 7, which is provided with notches 8, adapted tocooperate witli the pins 3 in the operation of tilting a car. Extendingfrom the body portion is an elongated arm 9, having'its vfree endextended at right angle as'at 10, and spaced from said arm 9 andextending from the body portion is a short arm 11. Pivotally mounted Yon the angle portions 9, 9, of the two end pieces is a transverse bar12, adapted to engage the top of a car, whilel pivoted to the outer endof the short arm is a transverse bar 13, arranged at right angle to thebar 12 and adapted to engage the side of a car.

The cradle is limited in its forward movement by a cable 14, secured atits ends to the cradle 4 andthe frame 1, as shown.

The railway car 18 to he tilted and dumped y is run on a platform 19,which seats in ways 19 in line with the track, the platform beingconnected by cables 20, passing over pulleys 21, on the cradle to asource of power (not shown). V

In operation, a car is run on the platform,

as shown in dotted lines at X in Fig. 1, then by applying power to thecable, the car is elevated to the cradle asshown to the position shownin dott-ed lines at B in Fig. 1.

'After the car is seated in the cradle, con. tinued pull on the cablerotates the cradle onits rockers, thenotches 8 engaging the pins 3. Therocking motion continues until the car is inverted, as shown in dottedlines at C, and the load is discharged.

After the loadis discharged, pull on the cable is released, and thecradle rolls back to normal position and the car is likewise lowered tothe track line.

It is to be noted that'the pivoted bars 12 and 13, readily accommodatethemselves to theside and top of the car, consequently the-v .end pieceshaving short extended arms on one side and elongated arms extending fromthe opposite sides parallel with the short arms, a bar pivoted to theouter end of the elongated arms to engage the top of the body of avehicle, a bar pivoted to the outer ends of the short arms to Vengagethe side of a vehicle body, and means for bodily lifting a vehicle toengage the bars and subsequently rotate the cradle on the inclined topof the.

frame to dump the load carried by the vehicle.

In testimony signed my name.
